Reactive Dye Printing
Reactive dye printing is a method of printing by Reactive dyes paste or wax by using mixture of Sodium alginate Gum, Soda ash, Urea and kerosin thereof to create a paste of colors. after printing of fabrics by thireactive dyesPrinting paste , the printed fabrics must be needed heat setting for drying at 130 degree temperature and curing at 180 degree Temperature. by this heating the 'Reactive printing'' paste will be permanently fixed on fabrics. after that the fabrics will need finish with softener for better hand feel. With a and a heat-activated printing additive, images can be permanently bonded to the substrate (typically textiles Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the ..., but can include cellulose, fibers, polyester, and even proteins). These reactions are generally ...

Reactive Dye
In a reactive dye, a chromophore (an atom or group whose presence is responsible for the colour of a compound) contains a substituent that reacts with the substrate. Reactive dyes have good fastness properties owing to the covalent bonding that occurs during dyeing. Reactive dyeing is the most important method for coloring cellulose fibers. Reactive dyes can also be applied on wool and nylon; in the latter case they are applied under weakly acidic conditions. Reactive dyes have a low utilization degree compared to other types of dyestuff, since the functional group also bonds to water, creating hydrolysis.Horst Tappe, Walter Helmling, Peter Mischke, Karl Rebsamen, Uwe Reiher, Werner Russ, Ludwig Schläfer and Petra Vermehren "Reactive Dyes"in Ullmann's Encyclopedia of Industrial Chemistry 2000, Wiley-VCH, Weinheim. Usage Reactive dyes had been tested in the late 1800s involving both adding functionalized dyes to the substrate and then activating the substrate first followed by fi ...

Textile Printing
Textile printing is the process of applying color to fabric in definite patterns or designs. In properly printed fabrics the colour is bonded with the fibre, so as to resist washing and friction. Textile printing is related to dyeing but in dyeing properly the whole fabric is uniformly covered with one colour, whereas in printing one or more colours are applied to it in certain parts only, and in sharply defined patterns. In printing, wooden blocks, stencils, engraved plates, rollers, or silkscreens can be used to place colours on the fabric. Colourants used in printing contain dyes thickened to prevent the colour from spreading by capillary attraction beyond the limits of a pattern or design. History Woodblock printing is a technique for printing text, images or patterns used widely throughout East Asia and probably originating in China in antiquity as a method of printing on textiles and later paper. As a method of printing on cloth, the earliest surviving examples from C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
